To all ywhom t may concern.'

Be it known that ll, Sani/10N THoMrsoN, a citizen of the United Statesof America, and a resident of Cedar Falls, Blackhawk County, lowa, haveinvented certain new and useful Improvements in Condensing Steamers, ofwhich the following` is a specification.

My invention relates to improvements in condensing Steamers, and theobject of my invention is to provide an apparatus capable of alternativeuse as a steam-condenser or a steam-storing means, and including aboiler with means for filling it.

This object l have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in rwhich Fig. 1 is a vertical central section of my improvedapparatus, and Fig. 2 is a horizontal section thereof, taken onthebroken line 2--2 of said Figql looking downwardly.

l Similar numerals of reference denote similar parts throughout theseveral views,

The numeral S denotes an open top vessel, hereinafter denominated theboiler, and which may preferably be constructed of glass, china or othermaterial which is practically non-corrosive by hot or boiling water orother liquids, rather than of iron or plated metal which will notsustain the action of such liquids or of the direct application of heat.

However, as a boiler made of such material is often frangible because ofthe slow conduction of heat therethrough when first applied, I havesupplied a contacting element 14, hereinafter described and explained,to serve in the equalization of the heat to prevent liability tocracking of the boiler.

The numeral 1 denotes a receptacle with open top closed by acentrally-orificed cover 9, and having hollow ears 2 on opposite sidesfor lifting it. The bottom plate 3 of this receptacle has a centralopening and is raised above the lower depending edge thereof, so thatthe upperedge of the boiler 8 ymay lit within the angle of the saidbottom plate and said depending part. About the central opening of thebottom plate 3 is a raised rim il.

The numeral 5 denotes a hollow cone mounted ooncentrically within thereceptacle 1 over said rimmed opening e, and has an apical orice inwhich may be tted a hollow cork 12, A like hollow cork 11 is fitted inthe central orifice 10 ofthe cover 9. The apex of the cone 5 terminatesvshort of the cover 9. A drain-cock 7 is in communication with thereceptacle 1 above the cone 5, and another drain-cock 6 opens into thepart of said receptacle about said rim 4, which serves as an annularcontainer for water of condensation.

The numeral 14C denotes a tubular metal body open at both ends,preferably made of copper or other metal which is a good conductor ofheat, and whose lower end has a short slot 15, said tube extending fromits contacting support on the bottom of said boiler through the cone 5and hollow corks l2 and 11 to have its open upper end above the cover 9to receive the iilling funnel-13.

lVhen used as a steam-condenser, thereceptacle 1 is filled about thecone 5 nearly n to the top with water, and water is placed in the boilerS by means of said funnel 13 and tube 1a, passinginto the boiler throughthe slot 15. Heat applied to the bottom of said boiler boils the watertherein, whose steam, rising, is condensed on the inner wall of the cone5, the water of condensation running down into the bottom of the conewhence it may be withdrawn as distilled water by way of the cock 6.

lVhen the apparatus is used as a steamer, no water is placed in thereceptacle'l about said cone 5, the hollow cork 11 in the cover 9 may bereplaced by a solid cork, and after the water in the boiler is heatednearly to boiling point the tube 14 is removed, (before replacement ofthe cork 11) to permit steam tov pass into the receptacle 1, whoseinterior may receive vegetables or other things to be steamed. c

As the tube 11i is a good heat conductor, it serves to equalize theinitial conduction ofy heat throughout the frangible boiler 8, toprevent fracture thereof. This insures longevity of the boiler, andpermits the use of any glass or china vessel or of an earthenwarecontainer for this purpose.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is:

1. A device of the character described, comprising an open top boiler, ahollow conical steam inclosure upon and in communication with saidboiler, having within its hollow an open top receptacle for water ofcondensation, having withOllt it a surroundcomprising an openl topboiler, a hollow oriing receptacle to Contain Cooling liquid immersingthe outer wall oi the conical inelesure, a slotted filling tubesnplmrtecl removuhly upon the bottom of said boiler und extending;`through said steam inelosnre7 und imlepenflent means for draining oil'theco'n-y tents of Suid inclosure and said receptacle.

2. A device of the character described,

iced conical steam inelosure upon and in oommunloatlon With said holler,having Without it a surrounding open-top receptacle7 means4 inelosureyand cover.

for draining said receptacle, n removable orificed @over for saidreceptacle, a tubular filler having one end slotted and resting on l'the bottoni of said boiler with ite upper part extending through theorifices of said conical inolosui'e :unl said Cover, and nieuns .i'orclosing' the. joints between said tube and said Signed at Waterloo,Iowa, this 30th day of June, 1921.
